Dear friends ,
i need a code about (Airfoil NACA 5 digit ) for FORTRAN ,to make an airfoil
also need graphic airfoil
i have equations ,please someone help me .m new for FORTRAN
thanks

Are you asking for help to write the FORTRAN code? If so, where are you having trouble?

yes .true
i have problem with equation .
how i should add the equation's to FORTRAN
the equation of curve line of airfoil is :

Yc= m/p**2(2px-x**2) ===================== from x=0 to x = p
Yc= m/(1-p)**2[(1-2p)+2px-x**2] ============ from x=p to x= c



Equation for calculate thickness upper and down the middle line of airfoil :

+ Yt = t/0.2(0.2969 RADICAL x - 0.1260 x - 0.3516 x**2 + 0.2843 x**3 - 0.1015 x**4)
-

the Equation of final dimensions of upper surface and down surface of airfoil :

Xu=x-Yt * SIN TETA
Yu=Yc+Yt * COS TETA
Xl=x+Xt * SIN TETA
Yl=Yc-Yt * COS TETA


Where TETA = ARCTAN[dYc/dx]






x= chord length
y= vertical length
t= MAX thickness
m= MAX curve
p=MAX leading edge curve

I have a example code but this code is for NACA 4 digit .i need NACA 5 digit also i need the Graphic picture of Airfoil :
i just want Design an Airfoil ..not flow making or analyze . simple 5 digit airfoil design also have graphic form
Code:

Without digging in deeper into the code, it looks like the framework is there for you to just change the equations. I'm not sure what your issue is specifically. Are you having trouble setting up the equations in Fortan? Do you have experience using fortran before?

Thanks
i don't have any experience for FORTRAN before im totally new in this
if you can make it simple for me .that i can understand and put my numbers to the code ,
that i exactly want is :
only make a 5 digit airfoil and have graphic form of this ( maybe with tecplot or something ... )
i don't need airflow equations ..or any extra thing ...only a design simple airfoil form just it .
i also have another better code .but i dont know how to send here

[batuning]

naca.zip
also another one
airfoil platform.zip

You should spend some time and learn the basics of the coding in FORTRAN if you want to modify it for your purposes.

yes exactly
thanks i will do it ,
and if you find something to help me ..please don't hesitate
